For best results, hydrate yourself when you wake up and wait 3 hours before testing. Tests just after waking will generally result in body fat readings several points higher.

10.) Center your feet on scale.The scale has four points of contact with your feet. It's recommended that users step onto the scale heel first and pay attention to placing your feet on the center of all four foot pads.
